Latest Updates products and Insights

The PET packaging industry is not one market — it is many. Each application has its own requirements for preform weight, neck finish, wall thickness distribution, material behavior, and downstream blow molding performance. A preform mold that works perfectly for water bottles may not be suitable for edible oil containers. A mold designed for carbonated soft drinks may not meet the needs of personal care packaging.

At LEIZHEN, we understand this diversity. We do not offer a one-size-fits-all preform mold. Instead, we provide full coverage across four major application categories: water, beverage, edible oil, and personal care. Each mold is engineered specifically for the demands of its target container type.

Water Bottles – High Cavity, Lightweight, High Output

Water bottles represent the largest volume segment in PET packaging. The key requirements are high cavity count, lightweight preform design, fast cycle times, and consistent quality across millions of shots.

LEIZHEN water bottle preform molds are designed for:

• High cavitation: 72, 96, 144 cavities and higher, matched to high-output injection molding systems

• Lightweight preform optimization: Thin wall design without compromising stretch blow performance

• Fast cooling: Optimized cooling circuits for short cycle times

• Consistent neck finish: PCO 1881, PCO 1810, and other water bottle standards

Our water bottle preform molds help customers achieve low cost per thousand preforms while maintaining reliable production runs.

Beverage Bottles – Carbonated, Juice, and Hot-Fill Applications

Beverage bottles face more demanding conditions than water bottles. Carbonated soft drinks require pressure-resistant neck finishes and uniform wall distribution. Juice and dairy products may require hot-fill compatibility or barrier properties.

LEIZHEN beverage preform molds are engineered for:

• Carbonated soft drinks: Strong neck finish design, consistent wall thickness to withstand internal pressure

• Juice and dairy: Heat-set compatible designs for hot-fill applications up to 85°C or higher

• Neck finish variety: PCO, ALaska, GME30.40, and custom specifications

• Material flexibility: Compatible with virgin PET, rPET, and barrier material blends

Our beverage preform molds deliver the performance and reliability that branded beverage producers require.

Edible Oil Bottles – Chemical Resistance and Dimensional Precision

Edible oil packaging presents unique challenges. Oil can interact with PET over time, and bottle dimensional stability is critical for filling line efficiency and shelf appearance. Preform weight and wall distribution must be precise to avoid stress cracking or deformation during storage.

LEIZHEN edible oil preform molds are designed for:

• Chemical-resistant design: Material selection and gate geometry that minimize degradation risk

• Precise wall distribution: Consistent material spread for bottle rigidity and drop impact resistance

• Neck finish accuracy: Secure capping interface to prevent leakage during transport and storage

• Long-term dimensional stability: Preforms that maintain shape through filling, sealing, and shelf life

Our edible oil preform molds are used by major oil bottlers who demand consistency and reliability over long production runs.

Personal Care – Cosmetic Finishes and Complex Neck Designs

Personal care packaging — including shampoo, lotion, soap, and cosmetic containers — demands high visual quality, complex neck finishes, and often smaller batch sizes with frequent changeovers.

LEIZHEN personal care preform molds are designed for:

• Cosmetic neck finishes: Custom thread designs, dispensing neck interfaces, and decorative features

• High visual quality: Clean gate vestige, no cloudiness or flow lines, consistent color acceptance

• Flexible cavity counts: Lower cavitation options for smaller production volumes and faster changeovers

• Quick maintenance: Easy-access components for cleaning and color changes

Our personal care preform molds help brands achieve the premium look and feel their products require, without compromising mold reliability.

One Factory, Four Application Specialties

LEIZHEN does not simply manufacture preform molds — we engineer them for specific markets. Our design team understands the differences between a water bottle neck finish and a carbonated soft drink neck finish. We know why an edible oil preform needs different wall distribution than a juice preform. We appreciate the visual quality demands of personal care packaging.

This application-specific knowledge is built into every mold we produce.

Full Coverage – What It Means for You

When we say LEIZHEN provides full coverage across water, beverage, edible oil, and personal care, we mean:

• You receive a mold designed for your specific container type, not a generic solution

• Our engineering team speaks your application language

• We can support multiple product lines from a single supplier

• Spare parts and technical support are consistent across all mold types

Cavity Configurations for Every Application

LEIZHEN offers preform molds in cavity counts ranging from 32 to 144 and higher. We tailor the cavity layout, cooling design, and hot runner system to your application and machine specifications.

Quality Across All Applications

Regardless of application, every LEIZHEN preform mold undergoes the same rigorous quality process: precision machining, CMM verification, dry assembly, and trial sampling on actual injection molding machines.

Technical Support You Can Rely On

LEIZHEN provides installation assistance, maintenance training, spare parts supply, and remote or on-site technical support for all four application categories. Our support team understands the specific challenges of water, beverage, edible oil, and personal care packaging.
